To alllfwhom'ztlmay concern:

VBe it knownthat I, Jol-IN J. DoLA'N, a

Vcitizen of theUnited States, residing at Campello, in the 'county ofPlymouth'and State of"h l'assachusett's7 have; invented certainImprovements inToe-Rests'for Last ingMachin'e's, ofV which the followingdescription,` in connection with .the accompanying drawings, isaspecification, like ref- 1 erence characters on the drawings indicatinglike parts inthefseveral figures. y u, Thisinventionrelatestor lastingmachines andfparticularly to artoe rest for `use upon i lasting machinesofthe bed'type.

Y p y 1Features `of1 the invention consist in a 'novel organizationI comprisinginstrumentalities tending to displaceV the tip seam,` a

holddown for applying vpressure to the shoe, and aL toe rest-having aresilient member that it willyield to pressure of thek shoe and engageVthe shoeL over a more extended area Vtodistribute `the pressure on the:tip seam.

As shown herein the rest-member is a'block ofresilient material; forexample, rubber,

havingl an approximately flat: toe engaging Y surface and centrallybeneath this surface ,is 'formed a recess extending from front to Thisrecess or cavityfdiminishes the ables the lateral portions of the pad to4come i into firmer "engagement with the -shoe 1 than they wouldotherwise do.

Another feature ofthe invention consists inA interchangeable meanslocated in therere'silienc'y of the toef pad to suit varying conditions.As` shown herein a spring having Specification of Letters Patent. gPfntdlebi 25; 1919, Application iiiedtiuiy so, 1:1315. serial No.42net..,

AAnother feature of the invention consists in `the lcombination with` ayielding pad member having a; recess or cavity therein and a hold-downfor applying` pressure to ,the shoe, .of asupport for the -pad membercomprising-a box in which the pad member fisrconin'ed, the recess orcavity in the pad 4member permitting `the pad member Ito be deformedinto theirecess in response topresdistribute theJ pressure substantiallythroughout; the extentl of the; tipv seam without `apply-ing "at anypoint an objectionable pressure.

Theopening also reduces the resistanceof .the lateral portions of the padas it provides aspace into which the rubber '.may be displacedfbypressure upon the pad.

It may be desirable, under some conditions,

to restore a` portion: of the resistance of the central part orV thepad. AThismay be done -by introducing into the opening a suitablespring. 20. Bythis means,the resiliency of -ther central portion ofthepad may be locally controlled in accordance with the requirements ofthe work.

Many of the advantages of my invention -may be secured .by forminga.single opening in the'pad, as'indicatedzin Fig. r4:,'which is smallerthan that employed when the spring 20 isY to bejnsedV and which vservesto reduce the resistance of the .centralportion` of the pad and avoidsthe objectional .effects oflexcessive pressure at this point.

Fig. 5 illustratesa still further'modificationl in which the number ofopenings is increased andY their size proportioned to the degree ofresistance required in the different portions of the pad. As shown, thelargerholes are arranged near the center and theholes rdiminish in sizetoward the lateral portions of the pad. It is to be .understood, ofcourse, that air spaces or cavities of any kind formed inthe Irubberwill, if properly located and of proper size, haveV asimilar effect andcome the scope ofthis invention. Iny Fig. 3 is shown` a spring'whichenwithin gages atA one .end Va button 22 having a -stud 24Lto enter thespring and a headed 55` projection 26fwhichmay belvulca'nized into theybody lofthe pad, -or otherwise-permanently secured therein.'AThe'opposite :end
